EDGlNG-CUT'TER.

SPECIFICATION forming part of Letters Patent No. 310,321, dated January 6, 1885.

Application filed July 28,1884. (No modvLl To all whom, it may concern:

Be itknown that l, ALEXANDER RoDGEns,

Muskegon, in the county of Muskegon and State of Michigan, have invented certain new and useful Improvements in Edging-Gutters,-

of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 is a plan of the machine with the saw-cover removed. Fig. 2 is a transverse vertical. section of the machine, showing the arrangement of the saws with relation to the stationary and swinging tables. Fig. 3 is a side elevation of the same. Fig. 4 shows an adaptation of the machine operating with a single table, and Fig. 5 represents a modification in which the wipers or devices which carry the edgings from the tables to the saws have a different form.

The object of this machine is to produce an apparatus that, with the least expenditure of floor-space, shall be capable of cutting up and disposing of the refuse from the largest mills in an efficient and economical manner; and the invention consists in the arrangement, preferably beneath the floor of the mill upon which the lumber'cutting saws are located, of an arbor carrying a series of circular saws, in connection with a stationary table upon which the refuse is received, and suitable devices for carrying said refuse from the tables to the saws, as will be hereinafter fully described.

111 the several figures of the drawings, A may represent the working floor of a saw-mill upon which the lumber-cutting saws are situated. Beneath this floor, and supported by posts B B, are placed the operative parts of the machine. 'llhesaw-arbor (1, provided with the series of circularsaws a a, is carried in journalboxes I), secured to the girts B; or, if desired, other suitable supports for these j ournal-boxes may be provided. A cover, D, having oppositcly-inclined sides, is placed over the saws, the top of said cover being preferably on a level with the mill-floor, so that an opening, A, is left upon each side of said cover through the floor for the passage of the edgings or other refuse to the stationary tables E, which are placed upon opposite sides of the saws, at l a point a little below the horizontal line of the saw-arbor, and extend inward from each ary tables, as at the right in Fig. 2 5 but when raised, as shown at the left of the same figure, extend across the opening and form, in connection with the inclined sides of the cover D, a hopper that receives and holds the edgings while the saws are cutting those which have already passed through to the stationary tables.

In order to give a proper movement and support to the swinging tables and at the same time carry the edgings upon the stationary tables forward to the saws, the shafts G G, carried in journal-boxes d d upon the girts B, and rotated in the manner hereinafter described, are provided with a series of arms or wipers, H H, which pass through the slots or openings 0 c in the stationary tables. Their outer ends coming in contact with the cleats c e, secured to the outside of the swinging trbles, cause the latter, as the shafts rotate, to be raised up, so as to form, in conjunction with theinclined sides of the cover,a hopper, which, as heretofore described, holds the edgings which may accumulate duripg the passage of th osc which may already be upon the stationary tables through the saws, the time during which the edgings areheld up by the swinging table depending upon the form given to the ends of the wipers, as these ends form a greater or less portion of the arc of a circle, and are consequently a longer or shorter time in passing a given point. As the rotation of the wiper shafts continues the edges of the wipers are brought in contact with the slabs or edgings upon the stationary tables, which are then carried forward to the saws, and be ing cutby the same drop from the inner ends of said tables into a receiver, or upon a suitable conveyor, by which they are carried to a place of deposit.

The method of imparting motion to the several parts of the machine which I prefer is by a belt from any suitable pulley upon the millshafting to the pulley I upon the saw-arbor, a smaller pulley, J, upon the same arbor, conveying motion through a belt to the pulley K upon the shaft L, which carries the pinion N, gearing into thelarge spur-gear P upon one of the wiper-shafts G. A similar spurgear, 1?, is placed upon the opposite wipershaft, and so arranged that the action of the wipers upon opposite sides of the machine shall be alternate, thus causing the edgings upon the stationary tables upon opposite sides of the saws to be moved forward in thesame manner alternately, thus equalizing the labor upon the saws,as well as other parts of the machine. V

In Fig. 4 is shown an adaptation of the machine to operate only upon one side of the saws, and with a single stationary table. Although containing substantially the same mechanical elements as thatheretofore described it evidently would have but half the capacity 1.0f the double machine, yet still. this would be sufficient to do the work of many millsiand would lessen the cost of construction.

In the modification shown in Fig. 5 a different form of the wipers is shown, the arms being three in number, the spaces between them forming arcs of circles which maybe provided with teeth.

In this form of the machine the edgingsare picked up from the stationary tables by the arms or wipers and carried forward to the saws resting upon said arms.

I am aware that it is not new to use a series of-circular saws mounted upon an arborto cut edgings. Neither is it new to employ rotating carriers to convey the edgings from a slotted table to the saws but the arrangement with these devices of a swinging table operated by the rotating carriers, causing an intermittent supply of edgings to the saws, and the combination therewith of the cover which protects them from injury by slabs or edgin gs falling from the floor, I believe to be new.

I claim as new and desire to secure by Let ters Patent the following:

1. In a sawing-machine for cutting edgings and like refuse, the combination, with the saws a a and a hopper having a swlnging table, F, adapted to form the bottom of said hopper when swung upward, and thereby give an intermittent supply of edgings to the saws, of a cover, D, arranged above the saws, and provided with an inclined side, substantially as described.-

2. In a machine for cutting edgings, the combination, with the saws a a, the cover D, and a hopper having swinging tables F, of a rotary shaft, G, provided with arms or wipers H H, adapted to alternately raise and lower saidtables, whereby the edgings are supplied to the saws intermittently, substantially as described.

3. In a machine for cutting edgings, the combination, with the saws a a and swinging tables F F, having cleats e c on their under sides, of the rotary wiper shafts G G and the arms or wipers H H, mounted thereon, substantially as described.

4. Inamachineforcuttingedgings,thecom- 7o saws and provided with oppositely-inclined sides, and a hopper having stationary tables E E and swinging tables F F, substantially ALEXANDER RODGERS.
